Mr Clarke is the longest serving of the group and one of 25 MPs in seats longer than six years who will receive £33,530, with the first £30,000 of the payment tax-free.

Ms Nash, along with 13 others who won their seats in 2010, will receive the lesser payment of £27,941.67.

All outgoing MPs are also entitled to claim up to £53,950 over the next two months to cover the closure of rented offices and to pay off staff.

According to rules set out by the Independent Parliamentary Standards Authority, a departing MP who stood for election and lost can also claim a “resettlement grant” to adjust to life after Westminster.

A member will be entitled to a month’s salary for each year’s service.
